LAMPE TIL LYSTERAPILIGHT THERAPY LAMP

Denne frembringelse angår en hospitalslampe til lysterapi og eventuelt også til almindelig belysning med henblik på at forbedre patienters helbred og forkorte indlæggelsestiden.This provision relates to a hospital lamp for light therapy and possibly also to general lighting in order to improve patients' health and shorten hospitalization time.

Det er velkendt, at sollys skaber liv, og at mennesket har brug for dagslys. Hvis man arbejder om natten og/eller sover om dagen, så opstår der forstyrrelser i hjernens biokemiske balance, hvilket på sigt skader helbredet. Det er for eksempel et faktum, at natarbejde øger risikoen for at få kræft.It is well known that sunlight creates life and that man needs daylight. If you work at night and / or sleep during the day, there will be disturbances in the brain's biochemical balance, which in the long run will damage your health. For example, it is a fact that night work increases the risk of getting cancer.

Får man for lidt dagslys, så skades både sind og sundhed, og det er velkendt, at mangel på dagslys påvirker såvel raske som syge mennesker psykisk og fysisk, herunder at det medfører depression og andre sindslidelser.If you get too little daylight, both your mind and your health are damaged, and it is well known that lack of daylight affects both healthy and ill people mentally and physically, including depression and other mental disorders.

Af samme grund benyttes lysterapi i behandlingen af depression, der primært skyldes en mangel på hjernens signalering med serotonin samt et lille underskud af signalstofferne dopamin og melatonin.For the same reason, light therapy is used in the treatment of depression, which is primarily due to a lack of brain signaling with serotonin as well as a small deficit of the dopamine and melatonin signaling substances.

Fordelen ved lysterapi er, at lyset specifikt regulerer hjernens melatonin, øger koncentrationen af serotonin og dopamin og sænker stresshormon i kroppen. Lysterapi er derfor den mest effektive og samtidigt den mest skånsomme behandling imod depression hos mennesker. Lysterapi kan imidlertid også kurere andre alvorlige hjernetilstande, der opstår pga. en biokemisk ubalance, eksempelvis stress, søvnforstyrrelse, panikangst, spiseforstyrrelser, adfærdsforstyrrelser, træthedssyndrom, og præmenstruelt syndrom.The advantage of light therapy is that light specifically regulates brain melatonin, increases the concentration of serotonin and dopamine, and lowers stress hormone in the body. Light therapy is therefore the most effective and at the same time the most gentle treatment against depression in humans. However, light therapy can also cure other serious brain conditions that result from a biochemical imbalance, such as stress, sleep disturbance, panic anxiety, eating disorders, behavioral disorders, fatigue syndrome, and premenstrual syndrome.

Den mest epokegørende nyhed er dog, at lysterapi modvirker cancer. Denne effekt skyldes flere mekanismer, bl.a. lysets kontrol over melatonin, der er en overordnet regulator af immunsystemet samt de fleste af kroppens hormoner (f.eks. køns-, vækst-og binyrebarkhormoner). Desuden er melatonin et antioxidant, der hæmmer celle- og DNA-skader, hvorfor melatonin modvirker udvikling og vækst af kræftceller. Således har melatonin-terapi vist sig, at bremse spredning af kræft hos patienter med ondartede cancere.However, the most epic news is that light therapy counteracts cancer. This effect is due to several mechanisms, including light control over melatonin, which is an overall regulator of the immune system as well as most of the body's hormones (eg, sex, growth and adrenal cortex hormones). In addition, melatonin is an antioxidant that inhibits cell and DNA damage, which is why melatonin discourages the development and growth of cancer cells. Thus, melatonin therapy has been shown to slow the spread of cancer in malignant cancer patients.

Med frembringelsen ønskes der tilvejebragt en lampe til lysterapi, det er let og hensigtsmæssig at anvende, fx på et hospital, til bedring afen sengeliggende patient.With the production, it is desired to provide a lamp for light therapy, which is easy and convenient to use, for example in a hospital, for the betterment of a bedridden patient.

Den nye lampe skal let kunne anbringes ved en sengeliggende patient og let kunne indstilles til at belyse patientens ansigt således, at patientens øjne modtager lys med et spektrum, der er tæt på i det mindste en del af naturligt dagslys’ spektrum.The new lamp should be easily positioned by a bedridden patient and easily adjustable to illuminate the patient's face so that the patient's eyes receive light with a spectrum close to at least part of the natural daylight spectrum.

Der er således frembragt en ny lampe til lysterapi, idet lampen har et lampehus, der indeholder en lyskilde, fx med en flerhed af lysdioder, til udsendelse af lys med et spektrum, der svarer til i det mindste en del af spektret for naturligt dagslys. Endvidere har lampen en computer til styring aflyskilden.Thus, a new lamp for light therapy has been produced, the lamp having a lamp housing containing a light source, for example with a plurality of LEDs, for emitting light with a spectrum corresponding to at least part of the spectrum for natural daylight. Furthermore, the lamp has a computer for controlling the sound source.

Lampen kan også anvendes til almindelig belysning i rummet.The lamp can also be used for ordinary lighting in the room.

Lampen er ny ved, at lampehuset er fastgjort ved en seng med en sengeliggende person, og at lampehusets position og orientering kan indstilles således, at lampehuset kan anbringes i en ønsket position i forhold til sengen og med en ønsket retning for lysudsendelse, fx sådan at den sengeliggende persons ansigt befinder sig i lampens lysfelt således, at den sengeliggende person modtager en del af det udsendte lys i sine øjne.The lamp is new in that the lamp housing is attached to a bed with a bed-resting person and that the position and orientation of the lamp housing can be adjusted so that the lamp housing can be placed in a desired position relative to the bed and with a desired direction of light transmission, for example such that the bedside person's face is in the light field of the lamp so that the bedside person receives some of the light emitted in his eyes.

For eksempel kan lampehuset være drejeligt fastgjort til en fod, via en eller flere forbundne arme, så at lampen kan flyttes frit rundt og placeres et vilkårligt sted på en vandret flade i rummet, fx på gulvet.For example, the lamp housing may be pivotally attached to one foot, via one or more connected arms, so that the lamp can be moved freely around and placed anywhere on a horizontal surface of the room, for example, on the floor.

Alternativt kan lampehuset være drejeligt fastgjort til sengen via én eller flere forbundne arme.Alternatively, the lamp housing may be pivotally attached to the bed via one or more connected arms.

Alternativt kan lampehuset være drejeligt fastgjort til et loft eller en væg i rummet ved sengen via én eller flere forbundne arme, fx til en skinne på loftet ellervæggen i lighed med andet af hospitalets udstyr, og så at lampen kan fastgøres i en vilkårlig ledig position langs skinnen.Alternatively, the lamp housing may be pivotally attached to a ceiling or wall in the space by the bed via one or more connected arms, for example to a rail in the ceiling or the wall similar to other hospital equipment, and so that the lamp can be fixed in any vacant position along rail.

Én eller flere afarmene kan have en indstillelig længde, fx teleskopisk.One or more forearms may have an adjustable length, eg telescopic.

Således kan lampehuset være drejeligt forbundet til den ene ende afen første arm, hvis anden ende er drejeligt fastgjort til en første ende for en anden arm, hvis anden ende kan fastgøres i et rum, hvorved lampehuset kan anbringes over en seng i rummet. De to drejelige forbindelser giver stor frihed til at indstille lampen i en ønsket position over en seng og med en ønsket retning for lysudsendelse, nemlig sådan at den sengeliggende persons ansigt befinder sig i lampens lysfelt således, at den sengeliggende person modtager en del af det udsendte lys i sine øjne. Lampen kan være forsynet med en fod, hvortil den anden arms anden ende er fastgjort, så at lampen kan flyttes frit rundt og placeres et vilkårligt sted på en vandret flade i rummet, fx på gulvet, eller lampen kan være forsynet med et fastspændingsorgan i den anden arms anden ende, så at lampen kan fastgøres til en skinne på en væg i rummet i lighed med andet af hospitalets udstyr, og så at lampen kan fastgøres i en vilkårlig ledig position langs skinnen.Thus, the lamp housing can be pivotally connected to one end of the first arm, the other end of which is pivotally attached to a first end of a second arm, the other end of which can be fixed in a space, whereby the lamp housing can be placed over a bed in the room. The two pivotal joints give great freedom to set the lamp in a desired position over a bed and with a desired direction of light transmission, namely such that the bedside person's face is in the light field of the lamp so that the bedside person receives a portion of the transmitted light. light in his eyes. The lamp may be provided with a foot to which the other end of the other arm is attached so that the lamp can be moved freely around and placed anywhere on a horizontal surface of the room, for example on the floor, or the lamp may be provided with a clamping member in it. the other end of the second arm so that the lamp can be attached to a rail on a wall in the room similar to other hospital equipment, and so that the lamp can be fixed in any vacant position along the rail.

Det er medicinsk set revolutionerende, at man med noget så enkelt som den nye lampe kan behandle alvorlige sygdomme hos patienter og forbedre både raske og syge menneskers helbred og humør.It is medically revolutionary that with something as simple as the new lamp you can treat serious illnesses in patients and improve the health and mood of both healthy and ill people.

Med lysterapi undgår man samtidigt de utilsigtede bivirkninger, der altid følger med farmaka og medikamenter.At the same time, light therapy avoids the unintended side effects that always accompany pharmaceuticals and medications.

Den nye lampe repræsenterer en konkret løsning på flere eksisterende, praktiske problemer, som generelt har stor relevans for sundhedsvæsenet - såsom på hospitaler, plejehjem, klinikker og institutioner m.fl. Den nye lampe løser for første gang en række problemer, idet den kombinerer patientbehandling, kurativ lysterapi og levering afen effektiv og tilstrækkelig belysning på et hospital.The new lamp represents a concrete solution to several existing, practical problems that are of general relevance to health care - such as in hospitals, nursing homes, clinics and institutions, etc. The new lamp solves a number of problems for the first time, combining patient care, curative light therapy and the provision of efficient and adequate lighting in a hospital.

Lampehuset kan have et vindue, som lyset fra lyskilden transmitteres igennem, og betjeningsorganer, der fx kan være anbragt langs med vinduets kant. Vinduet kan have en mat overflade således, at det udsendte lys er diffust og giver et ensartet belyst lysfelt, der er behageligt for den sengeliggende person.The lamp housing may have a window through which the light from the light source is transmitted, and controls which may, for example, be arranged along the edge of the window. The window may have a matte surface such that the emitted light is diffuse and provides a uniformly illuminated light field that is comfortable for the bed-resting person.

Ved hjælp af betjeningsorganerne, der fx kan indbefatte trykfølsomme knapper, kan den sengeliggende person tænde og slukke for lampen, og vil eventuelt også kunne justere lampen, fx det udsendte lys intensitet, eventuelt som funktion af tiden, varighed af behandling, natlys, læselys, etc.By means of the controls, which may include, for example, pressure-sensitive buttons, the bedside person can switch the lamp on and off and may also be able to adjust the lamp, eg the intensity of the light emitted, possibly as a function of time, duration of treatment, night light, reading light, etc.

Lampen kan have et betjeningsorgan til at udløse en alarm for at tilkalde hjælp.The lamp may have an operator to trigger an alarm to call for help.

Lampen kan med fordel have en føler til bestemmelse af, om der er en person til stede i lampens lysfelt. Føleren kan sende et signal til computeren med denne information.The lamp may advantageously have a sensor for determining whether a person is present in the lamp's light field. The sensor can send a signal to the computer with this information.

Computeren kan være indrettet til at styre lyskilden til kun at udsende lys, når der er en person i lampens lysfelt.The computer may be arranged to control the light source to emit light only when there is a person in the lamp's light field.

Føleren kan, eventuelt i samarbejde med computeren, bestemme øjnenes tilstand for en person i lampens lysfelt, såsom om begge øjne er åbne, det ene øje eller det andet øje er åbent, begge øjne lukkede, øjne kigger ligefrem, øjne kigger til den ene eller anden side, etc., og computeren kan være indrettet til at styre lampen i overensstemmelse med bestemte tilstande for øjnene.The sensor may, in conjunction with the computer, determine the state of the eyes of a person in the light field, such as whether both eyes are open, one eye or the other eye is open, both eyes closed, eyes are looking straight, eyes are looking at one or other side, etc., and the computer may be arranged to control the lamp according to certain conditions of the eyes.

For eksempel kan føleren, eventuelt sammen med computeren, være indrettet til at bestemme, om en person i lampens lysfelt er vågen, og computeren kan være indrettet til at styre lyskilden til kun at udsende lys, når der er en vågen person i lampens lysfelt.For example, the sensor, optionally with the computer, may be arranged to determine if a person in the lamp's light field is awake, and the computer may be arranged to control the light source to emit light only when there is a awake person in the lamp's light field.

Endvidere kan computeren være indrettet til at tænde og slukke for lyskilden i overensstemmelse med bestemte tilstande for øjnene, for eksempel kan computeren 4 4DK 2012 00039 U3 være indrettet til at tænde henholdsvis slukke lyskilden, når personen i sengen blinker med øjnene.In addition, the computer may be adapted to switch on and off the light source according to certain conditions of the eyes, for example, the computer may be arranged to switch on or off the light source when the person in the bed flashes with his eyes.

Endvidere kan computeren være indrettet til at aktivere en alarm i overensstemmelse med eb bestemt tilstand for øjnene, for eksempel kan computeren være indrettet til at aktivere en alarm, hvis personen i sengen blinker med et øje, eller hvis personen hurtigt fører blikket oppefra og ned og tilbage, etc.Furthermore, the computer may be arranged to activate an alarm in accordance with eb specific condition of the eyes, for example, the computer may be arranged to activate an alarm if the person in the bed is blinking an eye or if the person is quick to look up and down and back, etc.

Computeren kan endvidere være indrettet til at registrere den tid, den sengeliggende person modtager lysterapi på basis af information fra føleren, der registrerer om der er en person i lampens lysfelt, og eventuelt registrerer, om personen er vågen.In addition, the computer may be arranged to record the amount of time the bedside person receives light therapy on the basis of information from the sensor that detects if there is a person in the light field and, if possible, detects whether the person is awake.

Føleren kan omfatte et video kamera, som fx et web kamera, en infrarød detektor, eller en anden personføler, som det fx er velkendt inden for alarmsystemer.The sensor may comprise a video camera, such as a web camera, an infrared detector, or another personal sensor, such as is well known in the field of alarm systems.

Lampen kan have en indikator til indikation af den tid, en person i lampens lysfelt har modtaget lysterapi, fx siden et bestemt program for lysterapi blev påbegyndt, eller siden lampen blev tændt, etc.The lamp may have an indicator to indicate the amount of time a person in the lamp's light field has received light therapy, eg since a particular light therapy program was started or since the lamp was turned on, etc.

Lampen kan fordelagtigt være forsynet med et eller flere håndtag, fortrinsvis i et blødt materiale, til indstilling af lampens position og udstrålingsretning for det udsendte lys.Advantageously, the lamp may be provided with one or more handles, preferably in a soft material, for adjusting the lamp's position and radiation direction for the emitted light.

Lampen kan være udformet som en flad cirkulær skive.The lamp may be designed as a flat circular disc.

Computeren kan være indrettet til at udføre forskellige programmer for lysterapi med forskellige variationer af lysintensiteten, og eventuelt også spektrets form, som funktion af tiden.The computer may be adapted to carry out various light therapy programs with different variations in light intensity, and possibly also the shape of the spectrum, as a function of time.

Intensiteten af det udsendte lys kan variere som funktion af tiden på samme måde som intensiteten af naturligt dagslys varierer som funktion af tiden i det område, hvor lampen befinder sig.The intensity of the emitted light can vary as a function of time in the same way that the intensity of natural daylight varies as a function of time in the area where the lamp is located.

Endvidere kan computeren være indrettet til at styre lyskilden til ikke at udsende lys til lysterapi om natten.Furthermore, the computer may be arranged to control the light source so as not to emit light for night light therapy.

Computeren kan være indrettet til at styre lyskilden til at udsende rødt vågelys.The computer may be arranged to control the light source to emit red wavelength light.

Computeren kan være indrettet til at styre lyskilden til at udsende læselys med et spektrum, der ikke påvirker læserens døgnrytme.The computer may be arranged to control the light source to emit reading light with a spectrum that does not affect the reader's circadian rhythm.

Lampen kan have et interface, der er forbundet til computeren, og som kan forbindes til en ekstern computer, så at lampens computer kan sende data til og modtage data fra den eksterne computer. Interfacet kan være trådløst.The lamp may have an interface which is connected to the computer and which can be connected to an external computer, so that the lamp's computer can send data to and receive data from the external computer. The interface can be wireless.

5 5DK 2012 00039 U35 5DK 2012 00039 U3

Lampen kan være forbundet til den eksterne computer via et lokalt netværk. Via det lokale netværk kan lampen være forbundet til Internettet. Lampen kan også være forbundet direkte til Internettet. Dette kan fx være nyttigt for en person, der er sengeliggende i eget hjem.The lamp can be connected to the external computer via a local area network. Through the local network, the lamp can be connected to the Internet. The lamp can also be connected directly to the Internet. This can be useful, for example, for someone who is sleeping in their own home.

Programmer til lampens computer kan kommunikeres mellem lampens computer og den eksterne computer og eventuelt downloades og uploades via et netværk, som fx Internettet.Programs for the lamp's computer can be communicated between the lamp's computer and the external computer and possibly downloaded and uploaded via a network, such as the Internet.

Lampen kan fx overføre information om, hvorvidt der er en person i lampens lysfelt, og/eller information om lampens tilstand, fx om den er tændt, hvilket program, computeren kører, om lampen udsender dagslys, natlys eller læselys, hvor længe personen i lampens lysfelt har modtaget lysterapi.The lamp can, for example, transmit information about whether there is a person in the lamp's light field and / or information about the lamp's condition, eg if it is switched on, what program the computer is running, whether the lamp emits daylight, night light or reading light, for how long the person in the lamp light field has received light therapy.

Den eksterne computer, der kan være forbundet via Internettet, kan styre lampen via lampens egen computer.The external computer that can be connected via the Internet can control the lamp via the lamp's own computer.

Information om alarmen er aktiveret kan også sendes til den eksterne computer, eventuelt via Internettet.Information about the alarm being activated can also be sent to the external computer, possibly via the Internet.

Lampens lyskilde kan indeholde forskellige lysdioder, der hver især udsender lys af en bestemt farve, og den kan indeholde flerfarvede lysdioder, og den kan indeholde hvide lysdioder.The lamp's light source may contain different LEDs, each of which emits light of a particular color, and it may contain multicolored LEDs, and may contain white LEDs.

Lampen kan også indeholde lyskilder afen anden type end lysdioder.The lamp may also contain light sources of a type other than LEDs.

Lysdioderne kan være udvalgt for, at lampen kan udsende lys med et bestemt ønsket spektrum, fx et spektrum, der har en god effekt på en bestemt person eller en bestemt lidelse.The LEDs may be selected for the lamp to emit light with a specific desired spectrum, for example a spectrum having a good effect on a particular person or disorder.

Lampens computer kan eventuelt styre de forskellige typer lysdioder og eventuelt andre typer lyskilder, individuelt, så at computeren kan ændre formen af spektret for det udsendte lys, eventuelt som funktion af tiden. Hermed er det muligt at indstille spektrum fordet udsendte lys, så det kompenserer for forskellen mellem naturligt dagslys og anden indendørs belysning i rummet med den sengeliggende person.The lamp's computer can optionally control the various types of LEDs and possibly other types of light sources, individually, so that the computer can change the shape of the spectrum of the emitted light, possibly as a function of time. This makes it possible to adjust the spectrum of the emitted light to compensate for the difference between natural daylight and other indoor lighting in the room with the sleeping person.

Typisk vil en sengeliggende person opleve et øget velbefindende efter behandling med lysterapi med den nye lampe og dermed opnås typisk en hurtigere bedring.Typically, a bedridden person will experience increased well-being after treatment with light therapy with the new lamp and thus typically achieve a faster recovery.

Det er en vigtig fordel, at den nye lampe er indrettet til at udsende lys med en intensitet, der ikke er belastende for den sengeliggende person, men kan belyse personen i længere tid, fx gennem en hel dag, og fx følge intensitetsvariationen for det naturlige dagslys i området, hvor den sengeliggende person befinder sig. Der opnås 6 6DK 2012 00039 U3 formodentlig bedre resultater på denne måde end ved den kendte kortvarige (15-30 minutter) lysterapi med lys af høj intensitet.It is an important advantage that the new lamp is designed to emit light at an intensity that is not stressful to the sleeping person, but can illuminate the person for an extended period of time, for example throughout a day, and for example follow the intensity variation of the natural daylight in the area where the sleeping person is. 6 6DK 2012 00039 U3 will probably achieve better results in this way than with the known short-term (15-30 minutes) light therapy with high intensity light.

Herved opnås også minimal gene for eventuelle andre sengeliggende personer i samme rum.This also provides minimal nuisance for any other bed-resting persons in the same room.

Det kan være en fordel at anvende to lampehuse, der anbringes nogenlunde symmetrisk i forhold til midten af den sengeliggende persons synsfelt, når personen kigger ligefrem, og i kanten af, eller udenfor, den sengeliggende persons synsfelt. På denne måde kan hvert lampehus virkningsfuldt udsende lys af så lav intensitet, at det er muligt for den sengeliggende person ubesværet at foretage sig andre ting end at modtage lysterapi, såsom at læse en bog, se fjernsyn, betragte gæster, arbejde med en computer, osv.It may be advantageous to use two lamp housings which are positioned fairly symmetrically with respect to the center of the bedside person's field of vision when the person is looking straight ahead and at the edge of, or outside, the bedside person's field of view. In this way, each lamp house can effectively emit light of such a low intensity that it allows the bedridden person to effortlessly do other things than receive light therapy, such as reading a book, watching television, watching guests, working with a computer, etc.

Den nye lampe har fordelagtigt lysdioder, der udsender lys med en bølgelænge i intervallet fra 435 nm til 500 nm, og foretrukket udsender blåt lys med en bølgelængde på 464 nm, eller ca. 464 nm, som er en optimal bølgelængde for hensigtsmæssig styring af det menneskelige legemes produktion af melatonin.Advantageously, the new lamp emits light emitting diodes with a wavelength in the range of 435 nm to 500 nm, and preferably emits blue light having a wavelength of 464 nm, or approx. 464 nm, which is an optimum wavelength for appropriate control of the human body's production of melatonin.

Typisk udsender kunstige lyskilder meget lidt energi i bølgelængdeområdet fra 435 nm til 500 nm, og særligt ved 464 nm, i sammenligning med naturligt dagslys. Derfor oplever mange personer, der opholder sig inden døre, en mangel på lyspåvirkning med de symptomer, der er nævnt i indledningen.Typically, artificial light sources emit very little energy in the wavelength range from 435 nm to 500 nm, and especially at 464 nm, compared to natural daylight. Therefore, many people who stay indoors experience a lack of light exposure with the symptoms mentioned in the introduction.

Melatonin er et vigtig hormon for den menneskelige søvnrytme og er også vigtig for en balanceret psykologisk tilstand. Produktion af melatonin styres af døgnrytmen. Melatonin produceres af pinealkirtlen i mørke og undertrykkes i lys. Syntese og undertrykkelse er påvist at være særligt følsom overfor blåt lys selv ved lave intensiteter af det blå lys. Det er kendt, at balancen for melatonin og andre lysfølsomme hormoner er af betydelig vigtighed for en persons generelle helbredstilstand og velbefindende, og det er en vigtig egenskab for den nye lampe, at den kompenserer for manglende påvirkning af blåt lys, og derved forbedrer en persons velbefindende og generelle helbredstilstand.Melatonin is an important hormone for human sleep rhythm and is also important for a balanced psychological state. Melatonin production is controlled by the circadian rhythm. Melatonin is produced by the pineal gland in the dark and suppressed by light. Synthesis and suppression have been shown to be particularly sensitive to blue light even at low intensities of blue light. It is known that the balance of melatonin and other photosensitive hormones is of significant importance for a person's overall health and well-being, and it is an important feature of the new lamp that it compensates for the lack of blue light, thereby improving a person's well-being and general health.

Andre bølgelængder kan have særlig relevans, fx med det formål at påvirke endogen serotonin produktion.Other wavelengths may be of particular relevance, for example, with the aim of affecting endogenous serotonin production.

I det følgende beskrives eksempler på den nye lampe med henvisning til figurerne, hvori fig. 1 viser en sengeinstallation hvor den nye lampe er fastgjort til en skinne på en væg, så lampen kan fastgøres på et vilkårligt sted langs skinnen, og 7 7DK 2012 00039 U3 fig. 2 viser lampehuset set forfra.The following describes examples of the new lamp with reference to the figures, in which fig. 1 shows a bed installation where the new lamp is attached to a rail on a wall, so that the lamp can be fixed at any location along the rail, and 7 7GB 2012 00039 U3 fig. 2 is a front view of the lamp housing.

Fig. 1 viser en sengeinstallation, som den fx kunne se ud på et hospital. Den nye lampe 10 er fastgjort til en skinne 12 på en væg 14 ved en seng 16’s hovedende 18. Typisk anvendes skinnen 12 også til ophængning af andet hospitalsudstyr, fx til overvågning af den sengeliggende person.FIG. 1 shows a bed installation that it could look like in a hospital, for example. The new lamp 10 is attached to a rail 12 on a wall 14 at the head end 18. of a bed 16. Typically, the rail 12 is also used for hanging other hospital equipment, for example, for monitoring the bedside person.

Lampen 10 kan alternativt være forsynet med en fod, hvortil den anden arm 32’s anden ende 34 er fastgjort, eventuelt drejeligt, så at lampen 10 kan flyttes frit rundt og placeres et vilkårligt sted på en vandret flade i rummet, fx på gulvet 20 ved sengen 16.Alternatively, the lamp 10 may be provided with a foot to which the other end 34 of the second arm 32 is attached, optionally pivotal, so that the lamp 10 can be freely moved around and placed anywhere on a horizontal surface of the room, e.g. on the floor 20 at the bed 16th

Lampen 10 har et lampehus 22, der indeholder en lyskilde (ikke synlig), som i den viste lampe er lysdioder til udsendelse af lys med et spektrum, der svarer til spektret for naturligt dagslys. Endvidere har lampen 10 en computer (ikke synlig) i lampehuset 22 til styring af lyskilden. Lampehuset 22 er drejeligt fastgjort til den ene ende 24 af en første arm 26, hvis anden ende 28 er drejeligt fastgjort til en første ende 30 for en anden arm 32, hvis anden ende 34 er fastspændt til skinnen 12. Den anden arm 32 kan have en drejelig forbindelse ved fastspændingen til skinnen for at give yderligere frihed ved justering af lampehuset 22’s position. På denne måde kan lampehuset 22 anbringes på et hensigtsmæssigt sted over sengen 16 i rummet således, at en person i sengen 16 kan modtage lysterapi ved hjælp af lampen 10.

Hermed er det muligt at indstille spektrum for det udsendte lys, så det kompenserer for forskellen mellem anden indendørs belysning i det rum, hvor den sengeliggende person befinder sig, og naturligt dagslys.The lamp's computer can optionally control the various types of LEDs and possibly other types of light sources, individually, so that the computer can change the shape of the spectrum of the emitted light, possibly as a function of time. This makes it possible to set the spectrum of the emitted light to compensate for the difference between other indoor lighting in the room where the sleeping person is located and natural daylight.

Typisk vil en sengeliggende person opleve et øget velbefindende efter behandling med lysterapi med den nye lampe 10 og dermed opnås typisk en hurtigere bedring.Typically, a bedridden person will experience increased well-being after treatment with light therapy with the new lamp 10 and thus typically a faster recovery is achieved.

Det er en vigtig fordel, at den nye lampe 10 er indrettet til at udsende lys med en intensitet, der ikke er belastende for den sengeliggende person, men kan belyse personen i længere tid, fx gennem en hel dag, og fx følge intensitetsvariationen for det 10 10DK 2012 00039 U3 naturlige dagslys i området, hvor den sengeliggende person befinder sig. Der opnås formodentlig bedre resultater på denne måde end ved den konventionelle kortvarige (15-30 minutter) lysterapi med lys af høj intensitet.It is an important advantage that the new lamp 10 is designed to emit light at an intensity that is not stressful to the sleeping person, but can illuminate the person for an extended period of time, for example throughout a day, and for example follow the intensity variation for it. 10 10GB 2012 00039 U3 natural daylight in the area where the sleeping person is located. Probably better results are obtained in this way than with the conventional short-term (15-30 minutes) light therapy with high intensity light.

Det kan være en fordel at anvende to lampehuse, der anbringes nogenlunde symmetrisk i forhold til midten af den sengeliggende persons synsfelt og i kanten af, eller udenfor, den sengeliggende persons synsfelt. På denne måde kan hvert lampehus virkningsfuldt udsende lys af så lav intensitet, at det er muligt for den sengeliggende person ubesværet at foretage sig andre ting end at modtage lysterapi, såsom at læse en bog, se fjernsyn, betragte gæster, arbejde med en computer, osv.It may be advantageous to use two lamp housings which are arranged approximately symmetrically in relation to the center of the bedside's visual field and to the edge of, or outside, the bedside person's field of view. In this way, each lamp house can effectively emit light of such a low intensity that it allows the bedridden person to effortlessly do other things than receive light therapy, such as reading a book, watching television, watching guests, working with a computer, etc.

Computerens hukommelse kan indeholde forskellige programmer for lysterapi, der kan anvendes til forskellige individer og/eller til forskellige behandlingstyper. Computeren kan styre og registrere starttidspunkt og sluttidspunkt for en behandling og kan på basis af føleren 60 registrere den tid, den sengeliggende person har modtaget lysterapi, samt eventuelt den aktuelle type af lysterapi, herunder spektrets form og lysintensiteten.The computer memory may contain different light therapy programs that can be used for different individuals and / or for different types of processing. The computer can control and record the start time and end time of a treatment and can, on the basis of the sensor 60, record the time the bedside person has received light therapy, as well as the current type of light therapy, including the shape of the spectrum and the light intensity.
